Hi,

The article that I announced some time ago to be in the works is now
available in final form, for the very latest MDT OCL. Thanks to all who
provided feedback!


http://www.eclipse.org/articles/article.php?file=Article-How ToProcessOCLAbstractSyntaxTrees/index.html



Summary

The Model Development Tools Object Constraint Language (MDT OCL) project
provides the building blocks for Model-Driven tools to weave OCL
declarative specifications into software artifacts. We showcase some of
these possibilities, taking as starting point a plug-in to visualize OCL
abstract syntax trees (ASTs) in the form of annotated trees. This
example motivates some practical tips about patterns for OCL visitors,
including using Java 5 generics and achieving conciseness by letting MDT
OCL take care of the "walking" order. To really reap the benefits of
OCL-enriched specifications, tools in our modeling chain have to be able
to transform such expressions into the target software platform (e.g.
compile into Java, translate into SQL). Work in this area is summarized,
to ease jump-starting your own OCL processing project.


Regards,


Miguel

Hi, Miguel,

It looks great! This will undoubtedly help people to see the hidden value
of the AST and to work with it effectively.

Cheers,

Christian
